Further charges may be pending after a police investigation of a Macomb man last week lead to his arrest over possession of child pornography.

Macomb Deputy Chief Eric Lenardt told media Tuesday that police responded to the report of a subject in possession on Sept. 4, and after an investigation of the complaint and completion of a search warrant, Michael J. Boyer was arrested on Sept. 6.

Boyer, 23, was charged with three counts of child pornography, but Lenardt said "further investigation is being conducted." What was found from Boyer, the deputy chief said, were images on a personal phone.

The 23-year-old on Tuesday was lodged in McDonough County Jail on $50,000 bond.
